This makes us also use --param vect-force-slp=1 in addition to
-flto where LTO is supported. Note this only covers the subset
of tests not in one of the special naming-adds-option set. Note
neither g++.dg nor gfortran.dg vect.exp has VECT_ADDITIONAL_FLAGS.
This is a request for comments - the test coverage from this isn't
too big (it'll also trigger the CI)
* gcc.dg/vect/vect.exp (VECT_ADDITIONAL_FLAGS): Add
--param vect-force-slp=1.
